1. **State the problem:**
Gerald wants to transform the quadratic parent function $f(x) = x^2$ by reflecting it across the x-axis, stretching it vertically by a factor of 2, shifting it right by 3 units, and shifting it down by 4 units.
2. **Recall the transformation rules for quadratic functions:**
- Reflection across the x-axis: multiply the function by $-1$.
- Vertical stretch by a factor of $a$: multiply the function by $a$.
- Horizontal shift right by $h$: replace $x$ with $(x - h)$.
- Vertical shift down by $k$: subtract $k$ from the function.
3. **Apply each transformation step-by-step:**
- Start with $f(x) = x^2$.
- Reflect across x-axis: $-x^2$.
- Stretch vertically by 2: $-2x^2$.
- Shift right by 3: replace $x$ with $(x - 3)$, so $-2(x - 3)^2$.
- Shift down by 4: subtract 4, so $-2(x - 3)^2 - 4$.
4. **Final transformed function:**
$$g(x) = -2(x - 3)^2 - 4$$
5. **Match with given options:**
Option A matches the transformed function.
